Styrene "glass" is a remarkably strong, flexible, and lightweight product that takes the place of traditional glass. We use styrene instead of glass so our products may be shipped without breaking. While clear styrene is produced through manufacturing, styrene occurs in the environment and is a natural component of many common foods, such as coffee, strawberries and cinnamon. Should you prefer glass in our framed products, the styrene is easily removed and may be recycled with other plastics.
